Answer:
Use a graphing calc or desmos to help guide you.
Step-by-step explanation:
For a single payment with compound interest, the equation to use is F=P(1+i)^n where F is the value after n periods, P is the present value, and i is the interest rate.
If we want the final value F to double in 5 years, F is then equal to P then n=5. The equation is now:
2P=P(1+i)^5
2=(1+i)^5
i=14.87% per year
Answer:
B. 49
Step-by-step explanation:
Q; 9x^2 - 12x + 4
I graphed this equation to check A, B, C, and D for a solution and only B had a solution. So, I believe the answer is 49.
Answer:
9 gallons per minute
Step-by-step explanation:
If there are 54 gallons that came out of a pipe within 6 minutes, then we divide 54 by 6 to get how many would come out in 1 minute.
54/6 = 9.
C 118.2 just subtract 61.8 from 180
